Astronomy

Seasonal changes are caused by Earth's ........... around the sun.

• Orbit
• Revolution
• Rotation
• Tilt of axis

Movement of Earth around the sun.

• Rotation
• Revolution

What causes day and night?

• the earth's rotation
• the moons revolution around the sun
• the tilt of the earth
• the tilt of the moon's orbit

The earth has seasons because.......

• the temperature of the sun changes
• The earth rotates
• The earth is tilted
• The distance between the earth and sun changes

Where is the planet moving faster

• Position A to B
• Position B to C
• Position H to I
• Position I to J

Kepler's 2nd Law deals with 

• the shape of the planets' orbits
• the speed/area the planet travels 
• the length of time it takes the planet to orbit the sun

During precession, the Earth wobbles a little. This DOES change the angle of the axis.

• Nutation
• Precession
• Barycenter
• Revolution

The center of mass of an object

• Angle of Insolation
• Barycenter
• Equinox

Slow, circular movement at the top of Earth's axis

• precession
• barycenter
• revolution

The movement of one object around another is

• rotation.
• revolution.
• nutation.
• inertia.
